At South Mississippi Surgical Weight Loss Center, we employ several different bariatric surgery procedures that represent the best of what is available in the field. Of the procedures offered, the Roux-en-Y Gastric Bypass is the most invasive, but also the most effective. It is not for everyone and is reserved for those who are severely obese. We can help anyone who thinks that they may be a candidate for the surgery learn about its effects and evaluate the risks involved.

What is Roux-en-Y Surgery?

A Roux-en-Y Gastric Bypass Surgery involves rerouting the digestive tract to change the way the body holds and processes food. First, surgical staples are used to isolate a small section of the upper stomach, a step that will restrict the amount of food that can be consumed at one time. This small section is then connected to the middle section of the small intestine, known as the jejunum. The remainder of the stomach and the duodenum (the upper segment of the small intestine) are bypassed.

How does Gastric Bypass work?

At our Ocean Springs Office in Mississippi, we offer Roux-en-Y Gastric Bypass because it has the best rate of success among the surgical weight loss methods currently in use. The effectiveness of this procedure can be attributed to the combination of effects that it has on the body. By both restricting the capacity of the stomach and shortening the route that food takes through the intestine, Roux-en-Y Surgery results in rapid and significant weight loss.


All surgical weight loss techniques involve restricting stomach capacity. Because human beings have a primal drive to eat when we feel hunger, it is very difficult to force ourselves to stop eating before our stomachs are full and satisfied. This is why most diet plans are unsuccessful. They require people to attempt to overcome a basic human instinct.

However, by significantly reducing the size of the functional stomach, surgical weight loss allows a person to feel full and satisfied after eating a very small amount of food. In fact, it effectively prevents a person from overeating, because that very small amount of food is all that the stomach will hold.


In addition to restricting the stomach, Gastric Bypass Surgery also reduces the amount of calories that can be absorbed into the body by reducing the amount of small intestine that is used by the digestive tract.

In the process of digestion, the job of the stomach is both to hold food as it is eaten and also to break it down into a useable form. Once the food has been processed in the stomach, it enters the small intestine, where the calories and nutrients are absorbed into the bloodstream. Roux-en-Y Gastric Bypass leaves the uppermost section of the small intestine out of the digestive tract, thereby shortening the absorption process. The body has less capacity to extract calories from the food as it is being digested, which prevents the absorption and storage of excess calories as fat.


At South Mississippi Surgical Weight Loss Center, we perform bariatric surgery laparoscopically, which involves the use of a laparoscope, a long thin device with a minute camera on the end and thin surgical instruments to perform surgery without creating large incisions. This technique results in reduced pain and quicker healing time for most patients. However, although the external incisions from laparoscopic Gastric Bypass surgery are small and usually heal quickly, it is still an invasive procedure and it will take time to recover fully. Patients will typically remain in the hospital for up to two nights after surgery and must follow a strict dietary regimen during recovery.

Potential Risks of Gastric Bypass

Roux-en-Y gastric bypass surgery is an effective but invasive surgical weight loss technique. Immediate post-operative risks of this procedure include staple line leaks, pulmonary embolism (blood clots in the lungs), and pneumonia. In order to ensure that the healing process is progressing properly, Gastric Bypass patients are typically required to remain in the hospital for up to two nights after surgery.

After the recovery period, most bariatric surgery risks are related to the body´s newly limited ability to store and process food. Since Roux-en-Y Surgery involves bypassing a segment of the small intestine, the body may have trouble absorbing all of the nutrients it needs to function properly. Poor absorption of iron and protein can result in the lowering of total body protein or a predisposition to iron deficiency anemia. A reduction in calcium can cause metabolic bone loss in some patients, resulting in bone pain, loss of height, and fractures of the vertebrae, ribs, and hipbones. Chronic anemia can also occur due to a vitamin B12 deficiency. To prevent these bariatric surgery risks, SMSWLC Bariatric Team will recommend a daily regimen of vitamin supplements that is designed to make up for the body´s decreased ability to obtain vitamins from food.

Another condition, known as “dumping syndrome,” can occur as the result of rapid emptying of stomach contents into the small intestines. This can be triggered when too much sugar or large amounts of food are consumed. Although it is not considered to be life threatening, it is extremely uncomfortable. Symptoms associated with dumping syndrome are nausea, weakness, sweating, faintness, and diarrhea after eating. Preventing this side effect involves eating only small amounts at a time and avoiding foods that are high in sugar or fat.
